CAB-COUPLING.

Specification of Letters Patent.

Patented Oct. '7, 1919.

Application filed January 15, 1917. Serial No. 142,505.

To all whom it may concern Be it known that 1, JOHN G. TAYLOR, a citizenof the United States, residing at Findlay, in the county of Hancock andState of Ohio, have invented certain new and useful Improvements inOar-Couplings, of which the following is a specification, referencebeing had therein to the accompanying drawing.

My invention relates to improvements in car couplings, and moreparticularly to an improved locking block which is adapted to be usedwith a coupling of the'Janney type, such as is shown in my U. S. PatentNo. 1,098,135, dated May 26th, 1914. I

The object of the present improvement 1s to devise an improved means forholding the locking block in such a position that the knuckle may enterthe draw-head of the coupling and at the same time trip the holdingmeans and permit the lockmg block to move into place for lockingtheknuckle 1n the draw-head.

Another object of the present improvement is to so construct the lockingblock and its holding means, that upon moving the locking block torelease the knuckle the said holding means will automatically retain thelocking block in open position so that the knuckle may enter thedrawhead when it is desired to again lock the coupling.

Other objects and advantages of the present improvement will be setforth in the following description and drawings, in which Figure l is atop plan view of a coupling embodying my invention, showing the drawheadpartly broken away to show the knuckle and the locking block.

Fig. 2 is a perspective view showing the draw-head partly broken away,the knuckle in open position and the locking block in posit-ion toreceive the knuckle for locking the coupling.

Fig. 3 is an enlarged fragmentary vertical sectional view of thedraw-head and a side elevation of the locking block showing it held opento receive the knuckle.

Fig. 4 is a front view of Fig. 3.

Fig. 5 is a view similar to Fig. 3, showing the locking block in itslocked position for holding the knuckle in the draw-head.

Referring now to the drawings in detail, in which like referencenumerals designate similar parts throughout the several figures, 1represents the draw-head which is of the ordinary J anney type exteriorand needs no further description. The draw-head is provlded at its lowerend with a recess 2 to receive a locking block 3. This recess 2, asshown, is arranged directly in the center of the draw-head and thelocking block 3 is adapted to slide thereinto to lock the knuckle in itsinward position, as will be hereinafter more fully described. Thedraw-head at one side is provided at its upper and lower edges withoutwardly extending parallel horns, one of which 4 is shown. The knuckle5, which is of the character shown in my Patent No. 1,Q98,135 ispivotally mounted in a manner slmilar to the said patent between thesaid parallel horns. The knuckle moves downwardly into the slot 2 beyondthe said member 7, which is engaged by the said locking block therebypreventing the knuckle from swinging outwardly.

The locking block 3 comprises a pearshaped body portion having an eye 8in its upper end to which a suitable rod or lever 8 is connected forraising and lowering the said block to lock and release the knuckle 5. Aholding means, comprising a plate 9, having a hole 10 in its upper end,is pivotally attached to one side of the locking block by means of astub-shaft 11, carried integral with the locking block. The said plate 9has a portion 12 extending at right angles to the balance of the platewhich portion is provided with a tongue 13 that is adapted to oscillatewithin a slot 2 in the drawhead and to cooperate with a notch 15 "cut inthe front wall of the draw-head, which also forms the front end of theslot 2 In operation, when the knuckle is open, as

is shown in Fig. 2, the locking block 3 and its holding means willoccupy the position shown in Fig. 3. When the knuckle 5 is swunginwardly to lock the coupling, the portion 7 thereof, which is providedwith an engaging boss 14, will strike the end 12 of the plate 9 forcingthe tongue 13 out of the notch 15 in the end of the draw-head, thuspermitting the portion 7 to enter the draw-head, and the locking block 3to slide block oscillatable from a position at substan- 5 Copies of thispatent may be obtained for down in the position shown in Fig. 5, andlock the knuckle. In opening the coupling the reverse operation takesplace, the locking block being raised, the knuckle is freed and at thesame time the tongue 13 of the plate 9 due to the shape of the saidplate,

is. slid into the notch 15 in the draw-head,

thus holding the locking block 3 andholding means 9 in position to beengaged by the boss 14 on the portion? of the knuckle for looking thecoupling.

Having thus described my invention what I claim and desire to secure byLetters Patent is 1. A car coupling comprlsmg a drawhead, an osclllatinglocking block, the sald tially right angles to the draw-head into aposition substantially parallel thereto, and a holding member pivoted tothe block, said membermoved vertically by the oscillation of the saidblock whereby it is substantially parallel with the block when the saidblock isat right angles to the draw-head and is at substantially rightangles to the block'when the block is parallel with the draw-head.

2. A car coupling comprising a drawhead, an oscillatable locking block,and a holding member pivoted thereto and moved vertically by theoscillation of the said block.-

3. A car coupling comprising a' drawhead having a recess therein, anoscillatable locking blockat one side of the recess, and a holdingmember pivoted to the side of the locking block and vertically movablewithin the recess by the oscillation of the said block.

4. A car coupling comprising a draw-head having two'slots side by side,a locking block oscillatable in one slot, and a holding member pivotedto the side of the said block and vertically movable in the other slotby the oscillation of the locking block.

5. A car coupling comprising a drawhead, a locking block reciprocatablein a horizontal plane, and a holding member pivoted thereto and movablein a Vertical plane by the reciprocation of the locking block.

6. A car coupling comprising a draw head having a recess in the upperface thereof, a
